If there's one store that calls us back time and time again, it's H&M. It's basically a one-stop shop for affordable, on-trend items, and if that wasn't enough to turn you into a fan, perhaps Olivia Wilde [1] will. Not only has the star partnered with the brand, starring in its Conscious Collection campaign [2], but she also knows a thing or two about flawlessly rocking some of its most stylish pieces. Take the dress Olivia wore to the opening of a curated pop-up shop at H&M's Times Square location: the flowy, patterned design looks like a million bucks but doesn't top $300.

See her lovely look and campaign images in full ahead, then shop her outfit for yourself.
